I lived in Antibes for a year and have been to Eze. It's a great place to visit but it's VERY difficult walking and climbing. Not only due to the steep hill, but some areas with uneven stones/sidewalks.
If you have a car, St. Paul de Vence has a lot of the same "attraction" in terms of art and the feeling of a mid-evil rampart, but not quite as hilly (it's a bit more inland).
FYI, if you Google both of these locations with the word "pictures" you'll get lots of hits!
